Question

Does the equation x = 1 represent a function?How do I know if it represents a function if it doesn't have y axis to show if it is.

Answer 1

A function is a relation between variables y and x,

where theres only a y value for every x value

In this case x=1 . For every value of x = 1 ,there are infinite values for y , it can take any value , negative or positive.

So this is NOT a function
